means for inflating automobile tires by power derived from the automobile engine.

A further object of my invention is to provide a device as mentioned so constructed that ;the pressure within the tire can only be raised to a certain predetermined degree.

' A further object of my invention is to ro-. vide a device as mentioned which shal be operable to inflate the tire at such times only as the device is under the manual control of I the operator to the end that the tire shall not be ruptured through neglect on the part of the operator.

Other objects will appear hereinafter. With these objects in view my invention consists generally in an automobile tire inflater comprisingan air pump ada ted to be connected toand operated by the s aft of the engine when desired, a flexible hose of suit-.

able length to readily reach either of the sired, a flexible hose of suitab e wheels 0 the automobile and means for connecting the end of said hose to the valve tube of the tire. 3

My invention further consists in a tire inflater comprising an air pump, adapted to be connected to the shaft of the engine when delength extending from said pump and equipped with means at itsv free end to attach the same to the valve tube of a tire and so arranged as to normally exhaust into the atmosphere and suitable manually operated means for causing the same to exhaust into the tire. My invention further consists in various details of construction and arrangements of parts all as will be hereinafter fully described and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawing forming a part of this specification and in which,

Figure 1 is a diagram illustrating an automobile equipped with a tire inflater embody- 1 ing my invention, and Fig. 2 is a detail view lfipOIl an enlarged scale of the coupling mem- Referring to the drawing, 1 indicates the engine of an automobile, 2 the engine shaft and3 the transmissionshaft. Looselymounted upon the engine shaft, preferably between the engine and the fiy-wheel, 4 is an eccentrio, 5, for operating the piston of an air pump, 6.. 7 indicatesa clutch, operated by a lever, 8 for coupling the eccentric with the engine shaft when it is desired to inflate the tire.

It is obvious 'thatthe air pump will be used only when the automobile is at rest, hence, it is connected or driven from the engine shaft instead of the transmission shaft. I

'Any suitable means for driving the air pump from the engine shaft may be employed but I find that illustrated in the drawings, simple and efficient.

The pump, 6 is provided with a discharge pipe, 9 extending lnto a box or receptacle 10 arranged in the end of the engine casing, 11 as shown. Coupled to the discharge pipe, 9 is a flexible hose, 12 equip ed at the end with a coupling member, 13 tached to the plu of a tire. of suflieient lengt toreach any wheel of the automobile and when not in use is stored in the box, 10.

The coupling member, 13 is provided with y which it is at- The hose, 12 is a swivel nipple, 14 for attaching the device to the tire plug and is so constructed that it will operate only while a valve-thereon is manua y depressed by the o erator. The coupling member may be 0 an preferred construetion, but I prefer that i lustrated in Fig,

. 2. As shown therein, it comprises a tubular member, 15 secured to the hose, 12 by a coupling 16 and a transverse tubular member, 17 arranged at right angles thereto and forming therewith a T shaped member, the

nipple, 14 being arranged at one end of theportion, 17. The portion, 15 is provided with a discharge opening, 18 adapted to be closed by a valve, l9tarranged u on a lever, 20. The lever, 20 is pivoted to t e member, 13 as at 21 and is arranged parallel with the portion, 15. I

' It is obvious thatwhen the device is coupled to the tire and the engine started into operation, the air will exhaust through the d1scharge opening, 18 except when the lever,

20 is depressed. This is readily done by' grasping the (portion, and the lever 20,

' 24 and the valve, 22 is a spring, 26. The

' spring is set to valve, 22 is normally set to close the discharge. opening, 27 and the tension of the permit the valve, 22 to rise when the pressure in the device exceeds a certain degree. The tension of the springis adjusted by the nut, 25 and the position of-the valve is regulated by the plug, 24.

Having described my invention what I claim-as new and desire to secure by Letters Patent is:

1. An automobile tire infiater comprising an air pump adapted to be coupled to'the en- 'gine shaft when desired, in combination with a flexible hose of suitable length extending from said air ump and a coupling member on the free end of said hose for attaching the same to the tire plug, said coupling member comprising a tubular handle portion attached to said hose and a transverse tubular ortion arranged at the opposite end thereof orming a T s aped member, a-coupling nipple arranged at one end of said transverse portion a safety valve arranged. at the opposite end thereof, the first said tubular ortion havin a discharge opening, a valve or closin said opening and mounted upon a suitable lever, said lever being arranged substantially parallel with said handle portion and ada )tcd to be simultaneously grasped therewith to manually depress the valve to close said discharge opening substantially as described.

2. An automobile tire inflater comprising an air pump ada ted to be coupled to the engine shaft in com ination with a flexible hose and a coupling member from the free end of said hose for attaching the same to a tire plug, said coupling member comprising a tuular handle portion attached to the hose and a transverse tubular ortion arranged at the 0 posite end thereof orming a T shaped memb end of said transverse portion, a plug threaded in the opposite end of said portion, a threaded stem extending through said plug, a valve upon the inner end of said stem and fitting snugly within said transverse portion a eprmg interposed between said plug and sai valve and a nut threaded u )011 the outer end of said stem, and said tu ular portion.
